Task 1

Draw a picture of a person using a computer

You have 60 seconds

Task 2

Draw a picture of multiple people using a computer

You have 60 seconds

Drawing a line

This is what it typically looks like.

Drawing a line

How should a line behave if 2 people were using it?

Task 3. – Sketch out several design ideas

Drawing a line

How should a line behave if 2 people were using it?

Task 3. – Sketch out several design ideas– Now do it again after you:

• get a partner • manipulate a rubber band, string to help generate ideas

How people work together

Contrast restrictions imposed by– screen / mouse / keyboard vs.– paper / pencil

Single Display Groupware

Single Display Groupware

Co-located people work simultaneously on– a table, a wall display, or a monitor through– multiple mice, keyboards, multi-touch surfaces

Characteristics of SDG applications

Support to face-to-face interactionShared and coupled viewShared user interfaceShared feedback Multiple cursorsDifferent input devices No privileged devices

Slide adapted from A. Zanella presentation on Single Display Groupware

Why now?

Screen size increasing– large LED screens, HDTV, projectors, tabletop

displays, Smart boards…

Public vs. personal location– living rooms, family rooms, public walls

The Problem

GUI toolkits ignore multiple inputs, multiple users

Solutions

Research technologies that provide:

–multiple mice and keyboards

–multiple cursors

–multi-touch surfaces

• vertical displays

• tabletop displays

Instead of tool palettes– scatter tools atop the work surface– pick it up and use it– put it down when down
